This issue is difficult to resolve, and rating systems exist that are based on each of the extremes.

The power rating of a team is a calculation of the team's strength relative to other teams in the same league or division. The basic idea is to maximize the number of transitive relations in a given data set due to game ...

For AC-operated devices (e.g. coaxial cable, loudspeakers), there may even be two power ratings, a maximum (peak) power rating and an average power rating. [5] [6] For such devices, the peak power rating usually specifies the low frequency or pulse energy, while the average power rating limits high-frequency operation. [5]
